Cytomegalovirus (CMV) is the most common congenital infection. Intrauterine transmission may occur following primary (PI) or non-primary (NPI) maternal infection and result in both neonatal symptomaticdisease and long-term complications.The aim of the present systematic review and meta-analysis was the qualitative and quantitative comparison of neonatal symptomatic disease and long-term sequelae of congenitally CMV infected children born following maternal PI or NPI. Articles from MEDLINE and SCOPUS databases were systematically reviewed. Articles describing neonatal symptoms and/or long-term sequelae in infants and children with cCMV born to mothers following PI and NPI were eligible.From eligible articles, data on the prevalence of neonatal symptoms, sensorineural hearing loss (SNHL) or neurologic sequelae in children born following PI and NPI were extracted and statistically analyzed. Maternal infection status did not influence neonatal symptomatic disease (pooled Odds Ratio (OR) 0.83, 95 % CI [0.55; 1.27], p=0.397). Additionally, the two groups of cCMV infected children had similar risk of developing SNHL, bilateral SNHL or other neurologic outcomes. Importantly, these findings remained as such, when newborns identified through universal screening were separately analyzed. Finally, when data on symptomatic and/or asymptomatic newborns were evaluated alone, maternal type was not associated with outcomes examined. Considering available data, the universal screening of all newborns for CMV infection may be discussed as a perspective. The systematic review and meta-analysis were registered in PROSPERO (Prospero registration number: CRD42019125179).
